3. CKYPTURUS. 537 



Female. Similar to the male, but the lower parts less whitish and 

 more rufescent ; under tail-covcrts witli no white tips ; tlie bars on 

 the upper parts somewhat narrower ( Wied). It appears to me 

 that the female is to be distinguished by the upper parts being 

 blacker, with more regular and narrower rufous bars ; besides each 

 feather has two rufous bars. 



Younf/. Differs from the adult in having white dots on the fore- 

 head, behind the eyes, on the cheeks and upper parts ; the feathers 

 of the fore neck have blackish subapical bars and white tips ; also 

 the feathers of the lower parts have white tips, most conspicuous 

 on the lower flanks. 



Young in Jirst moult has no barrings on the upper parts, which 

 are olive-brown, more or less marked with black and dotted with 

 white.

19. Cryptiirus salvini. 



Similar to C. rariegafits, but the dark bars on the sides and 

 flanks less sharply defined and nearly obsolete on the sides, the 

 rufous and black bars of the ujiper parts less defined, the feathers of 

 the hack and mmp and upper wing-coverts with onlg one rxtfous har, 

 and the black tips much broader. 



One specimen, possibly a. female, has the rufous bars on the upper 

 parts better defined than in the other two adult birds, probably males. 



Young in Jirst moult. Similar to that of C. varlcgaius. and like 

 it has the upper parts olive-brown, dotted with white aud with no 

 bars.
